l v The Schedule referred to in these Letters Patent and making part of the s m Be it known that I, A BERT RUTTKAY, of the city, countyyand'state of New York, have invented a new and usetul Improvement in AsphaltOompositions, of which the following me specification.

' Nature and Objects of the Invention.

The invention relates to a composition of particles broken or pulverized into particles of the proper size, and capable. of being percolated byliquid or fluid matter, in comwith liuseed-oil,and with or without lit-barge. The object'ot: t-he'in i 'entioi is toproducc a compodesired; shapes, and-then hardened and used in a manner similar to and for similar purposes. GeneralDescription} t Theinvention consists of a composition of sand, chalk, lime, brick, suitable substance, of suflicient tenacit-y and hardness, with linseed-oil, to which may he added litharge, if it be desired, to

The following is aform ulaof the compositiom gir- One and one-half pounds chalk.

One-sixteeth pound litharge. k areplaced in a vessel, and .The .product maythen be to be coated with 1 the compo-;

mass, so that it willjbe impervious to'watr. I The ingredient common tothe invention is linseed- When it isdesired to {render the composition, when hardened; more compact, the relative q antit'y fully excluded when ftmay be' applied ored ingredients.

. In testimony th'at'I claim lowingthe composition todry and harden with rapi ity. admixture;

The formula above, or one embracing about the same ingredients, is suitable for use upon streets and pavements, in which use the ground is first cleared of loose earth, its surface being conformed to the desired shape; The composition, in a soft condition, is then spread 'over it evenly, and allowed to harden. The composition may likewise-he superposed on wood, stone, iron, brick, or composition paving. a -In preparing the composition for use roofi ng, the larger particles of-material greater should be careto the wallor roof, in the usual manner in which position it' vill harden, j "For'foot-pavements, taken, except that a material composedof smaller particles than coarse gravel should be used in its stead. This variety of: the composition is proper for the'man- 'ufacture of articles usually made ofclay; and, also,

whenin its soft condition, may be used asacernent or mortar.

The invention, when in its hardened state, cannot lie disintegrated by heat, and isnot affected by boiling water, V t

The composition maybe colored by the 'use of col- Claim. What I claim as my 1vention, and desire to s'e cure by Letters-Patent, is- 1 v Thecompositiori of gravel, or broken and-pulverized stone mixed, l itharge, chalk, and linseed-oil, as herein set forth, for a paving or roofing-material.
